GRAIN-BINDER.

Specification of Letters Patent. Patented June 20, 1916.

Application filed August 28, 1914. Serial No. 859,090.

'more particularly to a means for feeding the grain to the packing andbinding mechanism, and consists of certain improvements which are fullyset forth in the following specification and shown in the accompanyingdrawings which form a part thereof.

The object of the invention is to providea mechanlsm for maintaining thegrain in motion upon the deck of a binder so that it is .positively fedtoward the packing devices, thereby preventing the grain from becomingimproperly stacked up upon the deck in a more or less tangled condition.

It has for a further object to provide an auxiliary feeding device,adjacent the re-'- ceiving end of the deck of a grain binder, whichserves to keep the grain in motion toward the packing devices anddelivers the grain to said packing devices in the most effectivecondition for proper bundling and binding.

My invention also comprehends details of construction which, togetherwith the features above specified, will be better understood byreference to the drawings, in which Figure 1 represents a side elevationof a portion of a grain binder embodying my invention; Fig. 2 representsdiagrammatically a plan of the grain feeding and packing mechanism; Fig.3 represents a detail of the packer operating connections.

1 designates a portion of the binder frame having secured thereto theextended side bars 2 which form supports for the deck 3 as well as otheradjuncts of the mechanism. It will be noted that the frame 1 extends asuitable distance above the deck 3 for the purpose of forming a supportfor the breast frame 4:, which carries the knot-tying mechanism.

6 designates the cradle arm suitably mounted for oscillating movementupon the frame 2 and adapted to be driven by any suitable mechanism tocorrectly time its movements with respect to the packing and knottingoperations, but as this mechanism forms no part of the present inventionand has been described in my co-pending application, Serial No. 809,213,filed Dec. 29, 1913, I do not deem it necessary to here give a detaileddescription of the same.

7 designates suitable trip arms mounted in an operative manner upon theside bars 2 andforming a suitable movable frame for receiving the grainas it is fed along the deck and which also serves to cause actuation ofcertain automatic mechanism governing the needle arm 8, as will bereadily understood.

9 designates the packers which pack the grain as it is received upon thetrip frame 7 and cause it to be properly bundled against the cradle arm6 ready for the binding and tying operations.

The packers 9 are pivoted at 10 respectively to the cranks 11 and eachis preferably provided with suitable spurs 12 for the purpose ofincreasing the pressure of the grain upon the trip frame, and therebypositively insuring the actuation of the trip mechanism at the requiredtime. Each of the packers, in the present instance, is pro; vided withan extension 13 connected to a separate cross head 14, the one beingadapted to slide in the pivoted guide bar 15 at one side of the machine,while the other is similarly connected to a like guide bar at theopposite side of the machine, both of said bars being fixed to the rockshaft 16 which is journaled in the side bars 2 and operated by asuitable mechanism. The packer operating cranks 11 are mounted to rotatewith the shaft 17 so that the packers receive a movement which passesthem upwardly through the deck adjacent the receiving end of. the triparm 7, then a movement toward the cradle arm 6 and finally a return movement below the deck back to their original position. At the conclusionof the packing operation, the pivoted guides 15 are thrown downward tothe dotted position which has the effect of maintaining the upper endsof the packers 9 from passing so far above the table. This lattermovement is effected at the conclusion of the packing operation andremoves the packers from their normal operation, the pivoted guides 15are thrown free to carry the binding cord around the grain and to theknot-tying mechanism. The mechanism' for giving this desired movement tothe packers consists, in the present instance, of a crank arm 18suitably fixed to the rock shaft Y16 and pivotally conmounted to rockwith said shaft which rock 7 isreceivedupo'n thedeckfrom'any suitablenected through a link 19 with one end of the pivoted rack arm 20, thislatter being pivoted at 21 and having a locking shoulder 22 which isadapted to be engaged by the finger 23 of the connecting rod 24. Thepivot pin 25 which connects the link 19 and the rack arm 20 carries theapertured head 26 of a stem 27, this latter being slidingly mounted in afixed block 28 of the side bar 2, while between the saidblock and head26 there is a compression spring 29 which serves to complete a togglelike connection of the parts 19 and 20 whereby the packer guides 15 areshifted at certain times to the dotted line position of Fig. 1, therebylowering the packers to an inoperative position.

3O- designates a comparatively long link connected at one end to thewrist pin'8l of one of the cross heads 14, and at its oppositeendto acrank arm'82'fixed to therock shaft 83. This shaft extends transverselyofthe machine adjacent thereceiving end of the deck 3 and carries-aplurality of grain feeders 34, comprising radial pointed.

source, such as the conveyers 35, whereupon the feeders'Si and packers 9being in operation the grain is engaged by the former and advanced alongthe deck into the path of the packers. The action of the feeders 34 isto distribute the grain forwardly of the deck and prevent it fromstacking up at the receiving end of the deck in a tangled condition. Itwill therefore be apparent by employing one or more of the feedingmembers and imparting a rocking oscillating or equivalent movementthereto, that the grain will be kept positively in motion upon the deck,with the'result that the packers receive the grain in the propercondition for easy and uniform binding. It will further be seen thatwhen the packers are lowered below the deck during the operation of theneedle arm, the connecting rod 30 will be-drawn in a direction to varythe This action does not change the length of the stroke of the feedersbut shortens the stroke of that part of the feeders which is above thedeck, and consequently the cut grain which is fed forwardwhile theneedle arm is in its uppermost position is not distributed or fed asfast aS when the feeders are in their normal position. \Vhen the needlearm is in its uppermost position for binding'the grain, the feederstherefor move the grain along the deck against the rear portion of theneedle arm so that by the time this latter drops to its lowermostposition there will be a substantial sized bun- 'ated-as desirable, andwhile I have in the present instance shown and described the preferredembodiment thereof which has been found in practice to give satisfactoryand reliable results, it is to be understood that I .do not restrictmyself to the details, as the same are susceptible of modification invarious particulars without departing from thespirit or scopeof theinvention.

Having now described my invention, what I claim as new and desire tosecure by Letters Patent is '1. In a grain hinder, the combination of a:frame, a deck for supporting the grain, a plurality of packers forpacking the grain into binding position, a packer operating mechanism,a' rock shaft suitably mounted on said frame in fixed bearings, aplurality of feeder members fixed to said rock shaft and adapted tosimultaneously move through and over said deck to engage and feed thegrain to said packers, said feeder members stationary bearing securedadjacent to the deck and provldlng a fixed axls 1n which the arm isjournaled, and means to oscillate 15 said arm whereby the grain isforced within reach of the packers and prevented from becoming stalled.

In testimony of which invention, I hereunto set my hand.
